Embodiment 1
[0022] This embodiment prepares 100kg environment-friendly type dry powder interior wall paint as an example, and the preparation process is as follows:
[0023] Weigh according to the prescribed raw material formula, and the dosage is as follows:
[0024] Blast furnace slag powder 84kg
[0025] Titanium dioxide 5.5kg
[0026] Ash calcium powder 5kg
[0027] Redispersible latex powder 5kg
[0028] Water retaining agent 0.4kg
[0029] Defoamer 0.1kg
[0030] Put the above-mentioned raw materials into the mixer one by one, and stir thoroughly for 15 minutes. After fully mixing evenly, the environmentally friendly dry powder interior wall paint can be obtained; when using, add appropriate amount of water to fully reconcile and then paint and scrape.

Abstract
The invention relates to a method for preparing an environment-friendly interior dry powder coating from blast furnace slag micro powder serving as a main raw material, and belongs to the technical fields of chemical building materials and comprehensive utilization of solid wastes. The environment-friendly interior dry powder coating is prepared from the following raw materials in percentage by weight: 80 to 90 percent of the blast furnace slag micro powder, 3 to 18 percent of titanium pigment, 3 to 8 percent of ash calcium powder, 3 to 6 percent of redispersible emulsion powder, 0.2 to 0.6 percent of water-retaining agent and 0.05 to 0.2 percent of defoaming agent. The method comprises the following steps: weighing and mixing the raw materials in percentage by weight; and putting the mixed material into a stirrer, fully stirring for 15 minutes, and fully mixing uniformly to obtain the environment-friendly interior dry powder coating. When used, the environment-friendly interior dry powder coating is blended with a proper amount of water fully, and then the mixture can be coated and puttied on wall surfaces. The coating has good construction performance and operational effectiveness. The coating has strong bonding power, and washing, alkali and water resistance; and the coated film is difficult to crack. Moreover, the coating has no organic volatile matters, is nontoxic and tasteless, and has no harm to human bodies.
Description
technical field [0001] The invention relates to a preparation method of an environment-friendly dry powder interior wall paint using blast furnace slag micropowder as the main raw material, and belongs to the technical field of comprehensive utilization of chemical building materials and solid waste. Background technique [0002] With the development of current science and technology and the improvement of people's living standards, higher and higher requirements are put forward for their own living environment. At the same time, with the enhancement of people's awareness of environmental protection, indoor pollution and VOC have attracted more and more public attention. However, latex paints are widely used as architectural decorative coatings for interior walls at present. Latex paints use water as the dispersion medium, which has certain advantages in environmental protection. However, in order to improve the performance of latex paints, it is necessary to add certain A l...
